Answer:
15.73
Step-by-step explanation:
Straight angle is 180 degrees. So the given angles add up to 180.
(6x - 3) + (5x + 10) = 180
11x + 7 = 180
-7 -7
11x = 173

Answer:
1200<u>></u> 52+28x
Step-by-step explanation:
<u>Answer</u>
3.5 hours.
<u>Explanation</u>
The first step is to calculate the constant of proportionality.
t ∝ 1/n
t = k/n Where t = time, K= constant and n = number of people
t = k/n
k =tn
= 5×7 = 35
The equation becomes;
t = 35/n
for n = 10,
t = 35/10
t = 3.5 hours.
